A general method for rapid construction of metallocene-based hosts is described. Treatment of polyether bridged bis(diphenylacetylenes) with a source of cyclopentadienyl cobalt at high temperature leads, via macrocyclization and capture of the intermediate cyclobutadiene, to macrocyclic systems tethered to an integral metallocene platform. Equal yields of the two possible structural isomers, the products

In this work we describe the synthesis and the photophysical and electrochemical characterization of binuclear Pt-11 complexes. Using a modular click chemistry approach, we decorated different flexible bridging units with (bpy)Pt-II bisacetylides (bpy = 2,2'-bipyridine). Intramolecular excimer formation originating from Pt-II-Pt-II and pi-pi interactions was investigated by steady-state and time-resolved emission spectroscopy in dilute solution. We observed that linkers bringing the metallic centers in close proximity favor both ground-state coupling and excimer formation. These interactions lead to changes in the photophysical and electrochemical properties, which can be tuned by the choice of solvent.
